On the afternoon of September 3, 1812, 24 pioneers living in a settlement on the southern Indiana Territory frontier were murdered and mutilated by Indians. A tragic but familiar scene in the history of the westward expansion, the Pigeon Roost Massacre can be an effective teaching tool in Indiana studies. The massacre deals with the issues and emotions of both the settler and the Native American; therefore, it must be studied in context so that the student is not prejudiced by one side of the conflict. A history of events leading up to the massacre and its aftermath are recounted. A 13-item bibliography and three maps are included. The four lesson plans that accompany the history deal with (1) background material on the settler/Indian conflict in North America, especially the Indiana territory in the early 1800s; (2) the political decisions, national policies, and war strategies that resulted in attacks on settlers on the frontier; (3) perspectives of both sides of the conflict; and (4) details of the massacre, aftermath, and pursuit of the perpetrators. The handouts to be used with these lesson plans are provided and include time lines, maps, and articles. A list of 18 additional enrichment activities also is included. (JB)
